AM200/DX30(72) is a programmable frequency divider which is widely used for various applications in the fields of communication, instrumentation and test and control. The programmable frequency divider can be used to generate signals of different frequencies, from frequencies as low as 1 Hz all the way up to 200 kHz. It is an ideal tool for engineers and scientists who need to generate and process signals that have precise frequency characteristics.

The AM200/DX30(72) consists of a Programmable Frequency Divider and its associated Transmission Mode (TM) module. The Programmable Frequency Divider, or PFD, is an integrated circuit chip, which outputs digitally-controlled frequency division signals from a fractional clock based on the 3.68 MHz system clock. The TM module is used to interface the PFD with the system and allows the user to program the frequency division process.

The programmable frequency divider is used in many different applications such as frequency division multiplexing, pulse-width modulation, frequency synthesis, and digital phase-locked loop control. In frequency division multiplexing, the PFD is used to divide the input signal into multiple, non-overlapping outputs. In pulse-width modulation, the PFD is used to control the width of a rapidly changing pulse output. In frequency synthesis, the PFD produces an output signal of a desired frequency. Finally, the PFD is used to generate a digital phase-locked loop which is used to control the phase relationship between two or more signals.

The working principle of the AM200/DX30(72) is based on the divide-by-N principle. This principle states that when a pulse is transmitted into the PFD, it is divided into N number of equal portions. The PFD then maps each of these portions to a specific output frequency. The output frequency is then multiplied by a pre-determined amount to produce the desired frequency needed.

The AM200/DX30(72) has several advantages over other frequency dividers. It is fast, reliable and easy to program. It also has a low power requirement and the output signal is free from noise and jitter. In addition, it has a wide range of wavelength selection and can be used for divide-by-N ranging from 1 to 2000.

In summary, the AM200/DX30(72) is a versatile and reliable programmable frequency divider which is widely used for various applications in the fields of communication, instrumentation and test and control. It is based on the divide-by-N principle and has several advantages over other frequency dividers. It is fast, reliable and easy to program, has a low power requirement and produces an output signal that is free from noise and jitter.
